Solar Power: The Future Of Energy

I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
Solar energy is clean energy that does not affect our environment. Solar power utilizes the sun’s energy to produce electricity, unlike other sources of energy, which rely on continual mining for raw materials. Consequently, producing solar energy from the heat from the sun does not result into the annihilation of the ecosystem, compared to the extraction of fossil fuels (Bode, 2005). Therefore, with the use of solar energy, it will help keep the environment clean, thus help to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide. The use of solar energy will help save the worlds vegetation, and help prevent the effects of global warming in future. Therefore, solar energy is capable of becoming the world's future power supply as a clean energy source. If we choose to switch to solar energy in future, it will greatly save our environment because, it does not pollute our air and it is reasonably efficient. It will help reduce global warming, and thus a future green environment with no pollution from fossil fuels, and other conventional sources of energy. To add on that, it will also help in conserving our remaining fossil fuels so that it may not run out in the coming 100-500 years, as it has been predicted.
In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is...

History of Solar Energy

5796 words - 23 pages History of Solar Energy Many of us assume that the nation's first serious push to develop renewable fuels was spawned while angry Americans waited in gas lines during the "energy crisis" of the 1970s. Held hostage by the OPEC oil embargo, the country suddenly seemed receptive to warnings from scientists, environmentalists, and even a few politicians to end its over-reliance on finite coal and oil reserves or face severe economic distress and...

Renewable Energy: The Future of Energy

1052 words - 4 pages Many nations use energy generated from burning fossil fuels like oil, coal and natural gas. However, with the rapid growth of population, the demand for energy is increasing and this means burning fossil fuels to create energy generates emissions such as carbon dioxide and monoxide which in turn affects our environment, health and warms our planet. The long term use of fossil fuels is not viable, therefore, to combat the dependency on fossil...

Wind Power- the Future Energy Source

Abstract:
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.
Introduction:
Since 400-500A.D, people used windmill energy in farms for grain grinding and water pumping. In 1888, the first wind turbine that generated electricity was discovered by Charles F.Brush in Ohio, USA. However, there are limitations on speed.…show more content…

It drops almost 90 percent. (Brown 2005) (See Figure 2) However, the U.S was still behind Europe, because of some political and financial issues. Many European countries had started on building windmill projects. Europe comprised two-thirds of the global use of wind electricity-generating capacity. (Brown 2005). The leading countries that use wind power are Germany, Spain, USA, India and Demark. In addition, other countries are now started to utilize wind energy. Asia’s growth is up to 7000KW in 2005. (Florence 2006).
